Tooltip mode x on pie chart gives error

[teodorachiosa]

Expected behavior

The library lets me add scales and tooltip mode X on a pie/doughnut chart... which is odd in the first place.
If I don't get a compilation error when using TS, I would at least expect it to fail silently and do nothing. Instead I get console errors.

I also tried to use the chart as:

chartOptions: ChartOptions<'pie'> = { ... }

hoping to get some useful compilation errors for properties that don't make sense to be applied on a pie chart, but I run into this bug instead: #10896

Current behavior

Errors in the console:

Uncaught TypeError: t[a] is not a function

Context

We're working on a wrapper component over Chart.js which has a few look & feel customizations.
While testing the component out, we found that we can combine some properties even if they don't make sense (e.g. cartesian grid on pie/doughnuts charts).

You can combine properties because you can combine multiple chart types.

If you don't want this you can make it so that your wrapper component does not accept that kind of input.

In the version (4.4.4) that just got released it won't throw an error anymore.
